🔹 Why Protein Matters for Women

Protein plays a vital role in a woman’s body. It helps:

  • Build and repair muscle
  • Maintain healthy skin, hair, and nails
  • Support hormone function and bone density
  • Keep you fuller longer, aiding in weight management

According to Harvard Health, women should aim for a baseline of 0.8g of protein per kilogram of body weight. However, this changes significantly with age, activity level, and health goals.

Adult Women (19–50)46–60g per day
Pregnant Women71g+ per day
